Same here! It is VERY inconvenient!
The audio was perfectly synced (using a -1372ms delay) for months. And 2 weeks ago, I noticed that it was ahead of the video as we streamed Live, in spite of the -1372ms setting. Thinking it might be a change in one of their "streaming speed", I adjusted the sync offset parameters... but I went all the way to -1700ms to NO avail!!! The audio did crackle when I made the change but was still just as unsynced as before!
Please, help!
It is sooo tedious to have to edit our videos using a separate software and manually sync video to audio AFTER it streamed, and then reupload it to YouTube and Facebook, loosing all our metadata in the process.... :( :(
